To free her mother Jocelyn (Maxim Roy) from Valentine's (Alan Van Sprang) clutches, Clary Fray (Katherine McNamara) has to find the Mortal Cup. In Season 1 Episode 6 titled "Of Men and Angels," the shadowhunter finds a new ally who will help her locate it.

In the latest episode of Freeform's TV series "Shadowhunters," Clary will step into her past. Of course, this will prove to be a difficult task since all her memories have been erased. Nonetheless, she will find a new ally when she least expects it. Luke (Isaiah Mustafa) will tell her that there are several clues in the mundane world.

In the promo, Luke says, "She [Jocelyn] didn't think this was going to happen. She made provisions just in case it did."

Luke will provide more clues about her past by revealing the truth about his relationship with Jocelyn. This will be a shocking moment for fans of the show, because Clary might find out who her father is.

Elsewhere in the episode, Jace (Dominic Sherwood) and Simon will have a war of words. Reason? Clary, of course. The two will fight over the red-haired shadowhunter and the parabatai will tell Simon that he's been friendzoned all along and doesn't stand a chance with Clary.

In the promo, Jace calls Simon (Alberto Rosende) a mundane and this upsets him. Fans of the show will remember that Simon is anything but a mundane after his recent rendezvous with vampire Camille. It remains to be seen if Simon will make his new powers obvious.
